the pile of
water soaked garments in which he had been clothed when first brought
into the cabin. These lay in a heap on the floor.

"Maybe he's out on the after deck," ventured Jack still hopeful.

"Let's see," answered Tom. "If he is there, I'll cook and wash dishes
and scrub decks for a week on end!"

The after deck was empty. The visitor was nowhere in sight.

"Well, it looks as if he had come up out of the sea like a modern
Neptune and like Old Neptune has gone back into it again," Jack said,
his voice shaking. You don't suppose the fright he had turned his head
and made him commit suicide, do you?"

"Suicide your tintype!" stoutly scorned Tom. "Do you think that fellow
would commit suicide in a rowboat?"

"What do you mean?" questioned Jack wonderingly.

"I mean that our young pirate friend got one perfectly good square meal
of food, one entire new outfit of clothes and one rowboat from this
bunch of kindergartners. Then he opened the drip cock in our fuel tank
and sneaked out the back door and is gone."

"Good night," vociferated Harry. "It's as clear as mud! Look at what
that young villain has done! Why, he's a thief!"

"Easy now," admonished Jack. "We mustn't call him names. Maybe things
look black for him, but it may come out all right."

"Yea-ah!" scorned Tom. "When I can see the back of my neck it will. That
guy's crooked! That's what I believe."

"Me, too!" declared Harry. "I vote with Rowdy. He's usually pretty near
right when it comes to reading character!"

"Well, anyhow, this won't get us anywhere, and the Fortuna is rolling
like a loon. Let's see if Arnold can find bottom in the bilges yet and
then we'll connect up the spare tank and start out."

"Second the motion," declared Tom. "We ought to get going."

Suiting the action to the word the boys returned to the cabin to find
Arnold replacing the pump. The air was still heavy with the odor of
gasoline but Jack deemed it safe to operate the engine, since the
windows were to be left open giving a plentiful supply of air, thus
preventing danger of an explosion.

Tom was about to replace the hood over the engines after they had been
started when his eye caught sight of a piece of paper lying on the
floor. Hastily he kicked it aside and was about to pass to the pilot
house when Harry called his attention to the paper.

"Nice housekeeper you'd make," he taunted, "kick the dirt back under the
couch and let the sweepers get it! Why don't you
